Troy-based Reising Ethington Clients Win Patent Infringement Suit Brought by the Largest Steel Producer in the World


Troy, MI – February 8, 2011 – Reising Ethington P.C. attorneys David
Simonelli and Rick Hoffmann successfully defended two of the firm’s clients,
Severstal Dearborn, Inc. and Wheeling-Nisshin, in a patent infringement suit
filed by two French units of ArcelorMittal, the world’s largest steel
producer. During the trial, held in the United States District Court for the
District of Delaware, Simonelli and Hoffmann successfully argued that no
infringement had occurred by either of their clients and that the
ArcelorMittal patent is invalid. In the decision handed down January 14,
2011, the jury agreed and found the ArcelorMittal patent invalid and that no
infringement had occurred. The patent involved was United States patent
number 6,296,805, relating to aluminum coated boron steel.
The jury’s verdict came less than a year from the date the complaint was
filed. By negotiating with the court, a third defendant represented by other
counsel, and the plaintiffs, Simonelli and Hoffmann were able to quickly
bring this case to trial. As a result, Reising Ethington P.C. clients
Severstal Dearborn, Inc. and Wheeling-Nisshin, Inc. are now free sell their
steel in a competitive marketplace.
